SPECIFICATION forming part of Letters Patent No. 522,245, dated July 3,1894. Application filed June 7,1893- 'SerialNa 476,852. (No model.)

To all whom t may concern..-

Be it known that i, HARRY WHITE, of Syracuse,1n the county of Onondaga, in the State of New York, have invented new and use ful Improvements in Thimbles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in thimbles for encircling stove -pipes passed through partitions or other walls, and for similar purposes, and has for its object the production of a simple4 and practical device, which is cheaply manufactured, is durable and efficient in use, is readily adjusted to the desired length, and is rigid and firm when in operative position; and to this end it consists, essentially, in a thimble section comprising a hollow body portion formed of sheet metal and provided with an outturned flange at one end and a facing fused to the outer end of the inner periphery ofthe body portion and fused also to theouter face of the flange provided on said body portion. f

The invention furthermore consists in a series of engaging shoulders secured to one of the sections, and a locking member or arm secured to the other section for engaging said shoulders, and in the detailconstruction and arrangement of the parts, 'all as hereinafter more particularly described and pointed out in the claims. 4

In describingthis invention, reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is an elevation, partly in section, of a iiask having the body portion of one of the telescoping sections of my thimble shown in section in position therein for securement to the facing formed bythe entrance of molten material within the' flask. Fig. 2 is a vertical sectional view of my improved thimble shown as slightly extended. Fig. 3 is a horizontal sectional view, taken on line -3-3-, Fig. 2. Fig. 4.- is an isometric Vperspective of the locking member or arm secured to one of the sections, a portion thereof being broken away, and Fig. 5 is a similar isometric perspective of the locking member or arm secured to the opposite section.

It is well known that thimbles are fre quently used to encircle stove-pi pes and similar articles, and for like purposes. These thimbles are ordinarily constructed of telescoping sections, which are provided with facings secured thereto by rivets or other mechanical fastening means. The sections are also usually-held in their adjusted position by means of l springs, which are more or less liable to lose their efficiency, and to detract from the practicability of the thimble.

My invention consists of a thimble having a facing ot' cast' material fused to the outer end of the body portion of one or both of the sections composing the same and having its sections detachably secured together by rigid interlocking members or arms.

A B represent the sections of my improved thimble, and a b, facings fused at a b', to the outer edges of. the hollow body portions of the sections A B. The body portions of the sections, A B, are preferably composed of suitable sheet metal as tinned iron, and the facings a b, preferably consist of rings composed'o'f cast material as cast iron.

As clearly seen at Figs. 1,2, and 3 the body portions of the sections, A B, are provided attheir outer ends with flanges A B for furnishing additional surface to which the facings may be fused. As clearly seen at Fig.

l thebody portion of the section to which the facing is'to be secured, is supported in a iiask C withits upper edge at the base of the cavity or mold'c therein for receiving the molten material .which enters through the sprue hole c', and forms the cast facing secured to said body portion of the section.

The metal forming the cast facing is considerablygreater in bu'lk than that forming the part of the body portion of the section to which the facing is fused, and consequently the molten metal forming the cast facing fuses to the adjacent surface of the section body portion to be fused thereto before said molten metal cools and assumes its normal condition.

The facings, a. b, are preferably provided with substantially vertical and horizontal su rfaces a2 b2, di' b3, for securement respectively to the inner periphery of the outer edges'of the body portions of the sections A B, and to the outer face of the flanges ct b of said body portions. This construction of section is IOO economically manufactured, `and is evidently strong anddtrrable in use, since `the facing is virtually an integral part of the section. As is evident, however, only one of the sections of my thimble may be, if desired, provided with a facing fused thereto and the other sec- E tion may be unpiovided with a facing, or it may have a facing secured in any other well known manner. D is a locking member or arm secured to one of the sections of my improved thimble, and having its outer upright wail sufficiently k separated t-herefrom to permit entrance be tween the adjacent surfaces `of said sectioni and locking member, of the opposite section. As will `bereadilyiperceived upon reference to Fig. 2 the locking member or arm D isse- 1 curedto the ifacing of the section provided therewith `insteadof being secured directly to said section, but, as the facing forms es-'I sentially a portion of ithe'section, the locking i member orarm is, as is evident, virtually se-i cured tothe section. This locking member` orrarm is provided with a `number of shoulders d arrangedoneabove-the other, and `with a seriesiof slots or apertures d interposed between said shoulders. To facilitate its securement `the locking memberor arm is provided with a foot D having an opening forslot D2 therein tfor receiving a rivet d2 which l. also enters an opening a4 in `the facing a.. l E is'a lockinggmember or arm secured 'toi thesection B, and consisting of a foot and ai laterally projecting engaging end. The footi` of the :locking memberor arm E is provided with 4a recess or socket c for receivinga pro-g jection btof thesection B and with `1an open-i ing or aperture e' for `receiving a rivet -E,g` which, in connection with theinterlocking of 1 the socket or recess @and shoulder bteffectuE ally secures `the locking memberor `arm E iin operative position. fl The laterallylprojecting endof the locking member `or arm E is, as best seen at Fig. 3,; arranged in the same concentric plane as the slots or apertures d', in `the lockingmember i orzarm D, and is adapted toienter said slots or `apertures and interlock with the shoulders g d for .preventing lengthwise Iadjustment of: the thimble. At thefbase of the laterally `ex-` tending engagingend ofthe docking member? or `arm E `is a shoulder E2 for 4engaging the adjacent zfaces of the lockingimember orsarm D, and `limiting the partially revoluble move- 1 ment of fone section within the A:other, and proi vided in the youter-end of nsaid locking `memj ber or-:arm is anaperture E3 zfoi'zreceivinga suitable stop or pin F, which engages the face of the locking member or arm D opposite tor the face thereof engaged by the shoulder LE of the |locking memberor arm E.

.As ris clearly seen 'at Figs. 2 and 3 I preferably provide the ysection A with twooppof sitely `arranged flocking members or arms D and the oppositesection B with similarly arranged locking `members or arms E E having 1 oppositely extending engaging ends, but itis evident that onlyfone of each of saidlocking members or arms maj7 be used if desired.

When thimbles are used in new houses they are frequently placed in position before the partitions provided therewith are plastered, and the facings of thethimbles act asguides to limit the "thickness-of the plaster, and greatly aid the workmen in laying a uniform thickness of the plaster around the thimble openings iu the partitions, and producinga finished and workmanlike effect. It is necessary, however, to `adj ust the thimble Ato the predetermined thickness of the partition provided therewith, andconsequently l form one of the sections of my thimble with a suitable gage which, as hereillustrated,consists of ra series of ribs f provided upon `the locking member D. The position of ithe locking member relative to the ribs f enables the readyadjustmentof thesesections, and, as partitions are ordinarily of standard thickness side-walls from four to eight inches, and flooring -sixio twelve inches, but a limited number io'f ribs f are required, and the user readily deterininesupon theprecise one .which yit is desired to register with :the locking member D in `order to `adjust the athimble to the required length. It is evident, however, that grooves orother :distinguishing ymarksimay be :used instead of :the lribs f. t

The operation of mylinvention-will beireadily perceived from theforegoingdescriptionand upon reference to the drawings,andi`tiwill be particularly noted ithat fthe `same'isfeconomically manufactured, simple in l construction, is easily adjusted, firmly `iheld `-in its adj usted position, rand isstrong `and .durable 1n use.
